Abstract
This thesis conducts a comprehensive security analysis of cryptographic primitives
within the context of blockchain technology, focusing on MD5, Elliptic
Curve Cryptography (ECC), and digital signatures.
The first objective was to evaluate the security of MD5. The analysis revealed
that MD5, once widely used, is vulnerable to collision attacks, leading
to its deprecation in favor of more secure hash functions like SHA-256 for
blockchain applications.
